The seismic resistance of structures can be enhanced by using passive energy dissipation devices in order to dissipate earthquake energy. One of these devices is metallic yielding dampers which is low-cost, but highly-efficient. This paper aims to compare four key variables among eight metallic yielding dampers. Theses four parameters are equivalent viscose damping ratio, large load to weight, ductility and cumulative displacement. The dampers were selected based on the availability of the experimental data in the literature. As the first step of the methodology eight particular dampers with its load-displacement curve were carefully chosen to study. Three dissimilar last loops of force-displacement hysteresis were selected and drawn for each damper. Then the above mentioned parameters were calculated and compared to get results and draw conclusion. The outcomes reveal the relationship of the four studied parameters with each other. The results show there is a relationship between the mechanisms of energy dissipation with the specific range of equivalent viscous damping ratio in the studied metallic dampers.
